Nimrod AEW - The problems with the Nimrod AEW were more of the combination of the parts than the parts themselves. The positioning of the radar is the optimum method of mounting for
the most effective scanning. The aircraft radar did work it's just that the cooling of the systems in the narrow bodied aircraft couldn't be effected very well . Whilst many choose to knock it
I am sure that the radar for it's time in comparison with the Sentry was more advanced.Had we had ditched the Nimrod airframe and used something like a short bodied Airbus A300 we wouldn't be totally reliant on Boeing.
